Definitions

  • This disclosure relates to restorative dental implants and more specifically to zygomatic dental implants with an asymmetrical external feature.
  • Single tooth restorations e.g., crowns
  • an underlying structure e.g., a natural tooth prep, an abutment/implant assembly, etc.
  • this non-rotational supporting requirement is met in the normal course of preparing the natural tooth with a non-circular cross-section.
  • this non-rotational supporting requirement is met by preparing and/or using an abutment with a noncircular cross-section. This latter scenario can be more complicated due to the added connection between the dental implant and the abutment.
  • a dental implant is implanted into bone of a patient’s jaw (e.g., maxilla and/or mandible). While numerous design iterations have been marketed, overall there have been two types of dental implant-abutment interfaces within these assemblies: (i) an external -connection dental implant and (ii) an internal-connection dental implant.
  • the external-connection dental implant design typically includes a hexagonal boss (or another anti-rotation feature) protruding out of the dental implant’ s upper surface
  • the internal-connection dental implant design typically includes a hexagonal socket (or another anti-rotation feature) extending down and into the dental implant’s upper portion.
  • a corresponding abutment engages the dental implant in a non-rotational fashion and is typically secured thereto with a screw engaging an internal threaded bore.
  • a central or main axis of the tooth restoration and/or of the post of the abutment is at a non-zero angle relative to the central or main axis of the dental implant.
  • Angled dental implants typically include an angled mating surface (e.g., angled relative to horizontal) for connection with the abutment and an angled threaded bore (e.g., angled relative to vertical) for receiving the screw that holds the abutment to the dental implant at an angle relative to a central or main axis of the dental implant.
  • the inclusion of such internal angled features within the dental implant generally requires the dental implant to have a relatively larger sized outer diameter to accommodate such angled features therein. More specifically, the inclusion of such internal angled features can cause a portion or portions of an outer wall of the angled dental implant to have thickness that is much thinner than the rest of the wall forming the angled dental implant. As such, if the outer diameter of the dental implant is too small (even if just at a relatively small portion of the angled dental implant), the angled dental abutment may be prone to easily break/snap/fail.
  • angled dental implants have typically been limited to having at least a 4.5 millimeter outer diameter; however, such angled dental implants are not typically suitable for use in the anterior maxilla/mandible as the anterior maxilla/mandible in many patients is not able to support dental implants with such a large outer diameter.
  • the healing period of sinus augmentation takes about six months before implantation.
  • One of the most common complications of sinus augmentation is perforation of the sinus epithelium (a layer of“skin” of the sinus), which could be a result of sinusitis, excessive bleeding and delayed healing.
  • Zygomatic dental implants offer an alternative treatment option to sinus augmentation. Almost similar to trans-sinus angled dental implants, zygomatic dental implants are long implants that pass through the sinus or laterally to the sinus. While the tip of a trans sinus implant is positioned in the bone between the anterior sinus wall and the nasal cortical bone, a zygomatic implant anchors itself into the zygomatic process for stability.
  • Dental implants including zygomatic dental implants
  • dental implants often have rough surfaces such as threads.
  • Research has shown that osteoblastic cells (cells that develop bone) adhere more quickly to rough surfaces than to smooth surfaces. This property can also aid in osseointegration and guide movement of specific cell types and has the ability to directly affect cell shape and function.
  • a patient’s soft tissue comes into direct contact with the rough surfaces (e.g., with the threads) of the dental implant.
  • This direct interaction between the patient’ s soft tissue and the, for example, thread (e.g., micro thread, micro grooves, etc.) of the dental implant can cause irritation in the mouth of the patient.
  • a zygomatic dental implant includes a generally cylindrical body, an interior bore, an asymmetrical external feature, and a generally flat feature.
  • the generally cylindrical body has a coronal portion, a middle portion, and an apical portion.
  • the apical portion is for anchoring the zygomatic dental implant in zygoma bone of a patient.

  • the interior bore is formed in the coronal portion of the generally cylindrical body.
  • a circumferentially extending wall is defined by at least a portion of an outer surface of the generally cylindrical body and at least a portion of an inner surface of the interior bore.
  • the interior bore has a bore-central axis that is at an angle relative to the main-central axis of the generally cylindrical body.
  • the relative angle of the bore-central axis causes at least a first portion of the circumferentially extending wall to have a varying thickness about a circumference of the first portion.
  • the thickness of the circumferentially extending wall at the first portion varies from a thinnest portion adjacent to a first side of the generally cylindrical body to a thickest portion adjacent to a second opposing side of the generally cylindrical body.
  • the interior bore has a threaded portion for receiving a screw. The screw is configured to removably hold an abutment in engagement with the zygomatic dental implant.
  • the asymmetrical external feature is on at least a portion of the first side of the generally cylindrical body such that the asymmetrical external feature is configured to directly engage alveolar bone of the patient.
  • the asymmetrical external feature includes a plurality of circumferentially extending grooves such that (i) a circumferential length of a first portion of the plurality of circumferentially extending grooves decreases apically, (ii) a circumferential length of a second portion of the plurality of circumferentially extending grooves increases apically, and (iii) each of a third portion of the plurality of circumferentially extending grooves includes a gap.
  • the gaps collectively define a non-grooved area.
  • the non-grooved area is adjacent to the thinnest portion of the circumferentially extending wall of the generally cylindrical body.

L'invention concerne un implant dentaire zygomatique qui comprend un corps généralement cylindrique, un alésage fileté intérieur et un élément externe asymétrique. Le corps généralement cylindrique a une partie coronale et une partie apicale. Le corps généralement cylindrique a un axe central principal. L'alésage fileté intérieur est formé dans la partie coronaire du corps généralement cylindrique pour recevoir une vis configurée pour maintenir amovible une butée en prise avec l'implant dentaire zygomatique. L'alésage fileté intérieur a un axe d'alésage central. L'élément externe asymétrique est sur au moins une partie d'un premier côté du corps généralement cylindrique de telle sorte que l'élément externe asymétrique est configuré pour venir directement en prise avec l'os alvéolaire du patient. L'élément externe asymétrique comprend une pluralité de rainures s'étendant de manière circonférentielle.
